Immobilization of Motile Bacterial Cells via Dip-pen Nanolithography [PDF]
, 2010 A strategy to bind bacterial cells to surfaces in a directed fashion via dip-pen nanolithography (DPN) is presented. Cellular attachment to pre-designed DPN generated microarrays was found to be dependent on the shape and size of the surface feature ...

Anais da Academia Brasileira de Ciências, 2021 Ontogenetic shifts in food preference reduces intraspecific competition as immature individuals eat different food types than adults. This diet plasticity could facilitate species' ability to successfully invade and establish itself in a new environment,

Advanced Functional Materials, EarlyView.We introduce a nucleic acid nanoparticle (NANP) platform designed to be rrecognized by the human innate immune system in a regulated manner. By changing chemical composition while maintaining constant architectural parameters, we identify key determinants of immunorecognition enabling the rational design of NANPs with tunable immune activation profiles

The ultimate defense against piranhas [PDF]
Journal of Experimental Biology, 2021 ![Graphic][1] Picture the arch-nemesis of a fearsome piranha. What comes to mind? A giant, ferocious fish with teeth even more menacing than those of piranhas? A spiny, turtle-like fish that is as hard as a rock? Maybe something like an electric eel that could fight teeth with electricity?

A Termite‐Inspired Alternative to Cement
Advanced Functional Materials, EarlyView.A termite‐inspired composite of clay, cellulose, and lignin forms a dense fibrous network with concrete‐like strength (32 MPa) and superior elasticity, processed at ambient temperature. Abstract Clay combined with organic materials is used by termites as a strong and durable construction material for their mounds with minimal environmental impact. Here,

Advanced Functional Materials, EarlyView.Thermoelectric temperature sensors are developed that directly measure heat changes during optical‐based neural stimulation with millisecond precision. The sensors reveal the temperature windows for safe reversible neural modulation: 1.4–4.5 °C enables reversible neural inhibition, while temperatures above 6.1 °C cause permanent thermal damage.

Photophoretic MoS2–Fe2O3 Piranha Micromotors for Collective Dynamic Microplastics Removal
ACS Applied Materials and InterfacesMicroplastics are highly persistent emerging pollutants that are widely distributed in the environment. We report the use of MoS2@Fe2O3 core–shell micromotors prepared by a hydrothermal approach to explore the degradation of plastic microparticles ...

Advanced Functional Materials, EarlyView.Controlled laser‐drilling of embedded HfO2 membranes creates three layer nanopores with Gaussian‐shaped cavities sculptured in the supporting layers. These embedded solid‐state nanopores slow DNA translocation by 12‐fold compared to SiNx pores, enabling high‐resolution, label‐free detection of short DNAs, RNAs, and proteins.

Biocompatible parylene neurocages developing a robust method for live neural network studies [PDF]
, 2005 We present a refined method and design for fabricating parylene neurocages for in vitro studies of live neural networks. Parylene neurocages are biocompatible and very robust, making them ideally suited for studying the synaptic connections netween ...
